IMPROVEMENT IN BLANK-BOOKS.

part of this specification, and to the letters of referencev marked thereon, like letters indicating like parts whereever they occur. 4

To enable others skilled in the art to ,construct and use my invention,.l will proceed to describe it.

Figure l represents the side, and

Figure 2, the back of the-bookl i Blank-books of the best kind, used for business-purposes, are generally oinamented with strips or pieces of colored leather pasted in vaiious places on the leather covering the boards and backs of said books. The covering-leather is also ornamented with dark borders and 'rigures, produced by the hotrollers passed oversaid leather and burning in it .such ornaments.

This invention has for its object to imitate strips or pieces of colored leather pasted on the boards and backs of blank-books, by coloring the leather itself that covers the books with suitable colors, in places corresponding to the above said strips or pieces, thus presenting, in appearance, the book ornarnnted in the usual manner, but producing more durable and far cheaper articles. l

The invention consists also in doing away with the hot rollers, burning in the cover of said books dark borders and figures, and thereby damaging the leather, but producing the same kind of omaments by cold rollers and certain chemicals, as will be hereinafter fully explained.

When the blank-book is made and is ready to be covblack.

ered with leather, (which is tanned, but not colored,) strips, AA, of thin board are glued on the boards of the bok in places Where inblank-books now used strips of colored leather are applied; The book is then covered with the leather, which is rubbed with sandpaper in places, as A A and B B, andthe said places are sized and then painted over with any suitable colors, imitating strips or pieces of colored leather pasted on. The cover along the edges of strips AAis rubbed andpressed down with a suitable tool, so as to appear projecting above the boards.

To produce dark borders and ornaments, C C, a cold ordinaryroller is used, i connection with a sponge,

rag, or other convenient material attached to it, and impregnat'ed with acetate of iron,or other chemical suitable or the purpose, which sponge is continually wetting the projecting parts of the roller, so that whenY this is passed, under pressure, over the leather, said acetate of iron is deposited in the indentations formed in the leather by the roller, and acting chemically on the tannin What I claim as my invention, and desire to secure by Letters Patent, isy y The method of imitating ornamentalleather vstrips pasted on the buf-leather cover. of blank-'books by painting and bumishing upon the bu leather-itself with suitable colors, in places corresponding to' those where said strips are now produced by pasting on sep= arate pieces of colored leather, and in pressing dark borders or other; ornaments on their tanned-leather covers, substantially as'herein described. v
